# Some influential environment variables:
#  CC          C compiler command
#  CFLAGS      C compiler flags
#  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
#              nonstandard directory <lib dir>
#  LIBS        libraries to pass to the linker, e.g. -l<library>
#  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
#              you have headers in a nonstandard directory <include dir>
#  CXX         C++ compiler command
#  CXXFLAGS    C++ compiler flags
#  CCAS        assembler compiler command (defaults to CC)
#  CCASFLAGS   assembler compiler flags (defaults to CFLAGS)
#  LT_SYS_LIBRARY_PATH
#              User-defined run-time library search path.
#  CXXCPP      C++ preprocessor

# Host为目标主机，也就是准备安装平台的编译器去掉 -gcc
# Build为编译环境主机，也就是你的编译机器的交叉编译器，可执行 gcc -v 命令查看，我这里看得的是 Target: x86_64-linux-gnu

# System types:
#  --build=BUILD     configure for building on BUILD [guessed]
#  --host=HOST       cross-compile to build programs to run on HOST [BUILD]
#  --target=TARGET   configure for building compilers for TARGET [HOST]
